Question

Why the negative radical would before the positive radical?

Answer 1

In the first section of Algebra 1 we learned that

In the first section of Algebra 1 we learned that32=3⋅3=9

In the first section of Algebra 1 we learned that32=3⋅3=9We said that 9 was the square of 3. The square of -3 is 9 as well

In the first section of Algebra 1 we learned that32=3⋅3=9We said that 9 was the square of 3. The square of -3 is 9 as well(−3)2=(−3)⋅(−3)=9

In the first section of Algebra 1 we learned that32=3⋅3=9We said that 9 was the square of 3. The square of -3 is 9 as well(−3)2=(−3)⋅(−3)=93 and -3 are said to be the square roots of 9.

The positive square root is sometimes referred to as the principal square root. The reason that we have two square roots is exemplified above. The product of two numbers is positive if both numbers have the same sign as is the case with squares and square roots
